The active compounds according to the invention can be used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weed-killers. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are not wanted. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum.

Dicotyledon cultures of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita.

Monocotyledon weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cycnodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.

Monocotyledon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, ornamental plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields, in lawns, turf and pasture-land, and for the selective combating of weeds in annual cultures.

The active compounds according to the invention are very highly suited to the selective control of monocotyledon weeds in dicotyledon cultures, both pre- and post-emergence. They can, for example, be employed in cotton or sugar beet with very great success for controlling grass weeds.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine encapsulations in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents.

In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulfoxide, as well as water.

As solid carriers there are suitable: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates; as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulfonates, alkyl sulfates, arylsulfonates as well as albumen hydrolysis products; as dispersing agents there are suitable: for example lignin-sulfite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latexes, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Further additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.

The active compound according to the invention may be present in its customary commercial formulations and in the use forms prepared from these formulations, as a mixture with other active compounds, such as insecticides, attractants, sterilants, bactericides, acaricides, nematicides, fungicides, growth-regulating substances or herbicides. The insecticides, for example, include phosphates, carbamates, carboxylic esters, chlorinated hydrocarbons, phenylureas, substances produced by microorganisms, etc.

The active compound according to the invention may also be present in its customary commercial formulations and in the use forms, prepared from these formulations, as a mixture with synergistic agents. Synergistic agents are compounds which increase the activity of the active compounds without it being necessary for the synergistic agent added to be active itself.

The active compound content of the use forms prepared from the customary commercial formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

The compounds are applied in a customary manner which is appropriate for the use forms.

When used against hygiene pests and pests of stored products, the active compound is distinguished by an outstanding residual action on wood and clay as well as by good stability to alkali on limed substrates.

The active compounds according to the invention are active not only against plant, hygiene and stored-product pests but also, in the veterinary sector, against animal parasites (ectoparasites) such as scaley ticks, argasidae, scab mites, trombidae, flies (stinging and sucking), parasitic fly larvae, lice, hair lice, bird lice and fleas. For example, they exhibit an outstanding activity against ticks such as, for example, Boophilus microplus.

The active compounds according to the invention of the formula (I) are also suitable for controlling arthropods which infest useful animals in agriculture, such as, for example, cattle, sheep, goats, horses, pigs, donkeys, camels, buffalo, rabbits, chickens, turkeys, ducks, geese, bees, other pets, for example, dogs, cats, cage birds, aquarium fish, and so-called experimentation animals, such as hamsters, guinea pigs, rats and mice. By controlling these arthropods the intention is to reduce the occurrence of fatalities and of reductions in yield (of meat, milk, wool, skins, eggs, honey, etc.), so that the use of the active compounds according to the invention enables the keeping of animals to be more economic and more simple.

In the veterinary sector, the active compounds according to the invention are employed in a known manner by enteral administration in the form, for example, of tablets, capsules, drinks, drenches, granules, pastes, boli, by the feed-through method, as suppositories, or by parenteral administration, for example by injection (intramuscular, subcutaneous, intravenous, intraperitoneal, etc), implants, by nasal application, by dermal application in the form, for example, of dipping or bathing, spraying, pouring on and spotting on, washing, powdering and with the aid of shaped articles which contain active compound, such as collars, ear tags, tail tags, limb bands, halters, marking devices, etc.

When used for cattle, birds, pets, etc, the active compounds of the formula (I) can be employed as formulations (for example powders, emulsions, flowable compositions) comprising the active compounds in a quantity of from 1 to 80% by weight, directly or after dilution by a factor of from 100 to 10,000, or they can be used as a chemical bath.

The preparation and use of the substances according to the invention is illustrated by the examples which follow.

Use examples

Example A

Tetranychus test (OP-resistant/spray treatment)

Solvent: 3 parts by weight of dimethylformamide

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To prepare a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and with the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.

Bean plants (Phaseolus vulgaris) which are heavily infested by all development stages of the common spider mite or red spider mite (Tetranychus urticae) are treated by being dipped into the active compound preparation at the desired concentration.

After the desired time, the destruction is determined in %. In this context, 100% means that all of the mites have been killed; 0% means that none of the mites have been killed.

In this test, for example, the compounds according to Preparation Examples I-2 Ba-1 and I-2 Bc-1, at an active compound concentration of 0.1%, which was chosen by way of example, brought about a destruction of at least 98% after 7 days.

Example B

Test with Boophilus microplus resistant/SP resistant Parkhurst strain

Test organisms: adult sucked-up females

Solvent: dimethyl sulfoxide

20 mg of active compound are dissolved in 1 ml of dimethyl sulfoxide; lower concentrations are prepared by dilution with the same solvent.

The test is carried out in 5-fold determinations. 1 μl of the solutions is injected into the abdomen, and the organisms are transferred to dishes and kept in a climate-controlled area. The activity is monitored, after 7 days, by inhibition of ovipoisition. An activity of 100% indicates that none of the ticks laid eggs.

In this test, for example, the compounds according to Preparation Examples I-2 B-a-1, I-2 B-b-1 and I-2 B-c-1 showed an activity of 100% at an active compound concentration, chosen by way of example, of 20 μg/organism.
